Here's a method I wrote a while back which should do what you want. I've placed it inside a console app for testing purposes. Notice that it optionally supports UK style number/word translation i.e. One Hundred and Twenty Four as opposed to One Hundred Twenty Four. However it doesn't support numbers with decimal points. using System; class Program { static void Main() { string input; int number; bool isValid; bool isUK = false; Console.WriteLine(
Enter '0' to quit the program at any time
); while(true) { Console.Write(
Use UK numbering y/n : ); input = Console.ReadLine(); if (!(input.ToLower() == y || input.ToLower() == n)) Console.WriteLine(
 Must be 'y' or 'n' please try again
); else { if(input.ToLower() == y) isUK = true; Console.WriteLine(
); break; } } do { Console.Write(Enter integer : ); input = Console.ReadLine(); isValid = int.TryParse(input out number); if(!isValid) Console.WriteLine(
 Not an integer please try again
); else Console.WriteLine(
 {0}
 NumberToText(number isUK)); } while(!(isValid && number == 0)); Console.WriteLine(
Program ended); } public static string NumberToText(int number bool isUK) { if (number == 0) return Zero; string and = isUK ? and  : ; // deals with UK or US numbering if (number == -2147483648) return Minus Two Billion One Hundred + and + Forty Seven Million Four Hundred  + and + Eighty Three Thousand  + Six Hundred  + and + Forty Eight; int[] num = new int[4]; int first = 0; int u h t; System.Text.StringBuilder sb = new System.Text.StringBuilder(); if (number { sb.Append(Minus ); number = -number; } string[] words0 = { One  Two  Three  Four  Five  Six  Seven  Eight  Nine }; string[] words1 = {Ten  Eleven  Twelve  Thirteen  Fourteen  Fifteen Sixteen Seventeen Eighteen  Nineteen }; string[] words2 = {Twenty  Thirty  Forty  Fifty  Sixty  Seventy Eighty  Ninety }; string[] words3 = {Thousand  Million Billion }; num[0] = number % 1000; // units num[1] = number / 1000; num[2] = number / 1000000; num[1] = num[1] - 1000 * num[2]; // thousands num[3] = number / 1000000000; // billions num[2] = num[2] - 1000 * num[3]; // millions for(int i = 3; i > 0 ; i--) { if (num[i] != 0) { first = i; break; } } for(int i = first ; i >= 0 ; i--) { if (num[i] == 0) continue; u = num[i] % 10; // ones t = num[i] / 10; h = num[i] / 100; // hundreds t = t - 10 * h; // tens if (h > 0) sb.Append(words0[h] + Hundred ); if (u > 0 || t > 0) { if (h > 0 || i if (t == 0) sb.Append(words0[u]); else if (t == 1) sb.Append(words1[u]); else sb.Append(words2[t-2] + words0[u]); } if (i != 0) sb.Append(words3[i-1]); } return sb.ToString().TrimEnd(); } } // end class
